DESIGN: Three multiple-pass 24-hour recalls were obtained over a 14-day period to estimate mean energy intake. Total energy expenditure was measured over the same 14-day period under free-living conditions using the doubly labeled water technique.he correlation between individual measures of energy intake and total energy expenditure was not statistically significant (r = .25, P = .24). CONCLUSIONS: Data from 3 days of multiple-pass 24-hour recalls were sufficient to make valid group estimates of energy intake.

Fortunately, there exists a simple theory for determining molecular geometries at a qualitative level, which is useful for understanding the basic shapes of molecules. This theory is known as the VSEPR theory, which is an acronym for the valence shell electron pair repulsion theory. It is useful for estimating the shapes of molecules for which there is a central atom bonded to several other atoms surrounding it.
